Chemical Properties

Formula Weight
Melting point
Storage & Sensitivity
Keep Cold. Hygroscopic. Air Sensitive.
Soluble in water.


1-Butylboronic acid is used as a reagent for preparation of volatile derivatives of diols, e.g. carbohydrates, for GC and mass spectrometry and to prepare chiral oxazaborolidines. It is a precursor to unsymmetric borinic acids, which are inhibitors of serine proteases. Can be used as a transport carrier in membrane-based sugar separations and as an analytical reagent in the determination of serum glucose.


Keep container tightly sealed. Store in cool, dry conditions in well sealed containers. It is hygroscopic in nature. Incompatible with oxidizing agents. Store under dry inert gas.

In combination with (S)-(-)-ɑ,ɑ-Diphenyl­prolinol, L09217, or its enantiomer (9218), oxazaborolidine catalysts are generated in situ, for use in highly enantioselective reductions: Tetrahedron Lett., 33, 4141 (1992).
